Keith Urban, Lady Antebellum, Tim McGraw, Sara Evans, Ronnie Dunn and Alabama are among the first stars to sign on for a CMT benefit concert to help the victims of last week's tornadoes.  The 90-minute show was spearheaded by Hank Williams Jr., who went to the channel with the idea.  He says, "Alabama is home...I am really pumped about helping.  I want to raise a lot of money, and thanks to my good friends, we are going to be able to make a difference."

The show will air on May 12th on CMT and CMT.com at 8pm (Central).  Proceeds will go to the American Red Cross Disaster Relief Fund.
